摘　　要：详述了在工程应用中选择小波基所依据的几个重要特征和参数，研究了四类样条小波和它们生成的小波基的几种重要的特征（消失矩、局部化特性、线性相位等）参数；并研究了它们对一维信号的直接小波变换。Several important characteristics and parameters of chosen wavelet bases were described in detail. Some important properties and parameters of wavelet bases (wavelet moment, vanishing moment,localization property,linear phases, etc.) and four types　splines wavelets were researched. Direct wavelet transforms of onedimensional signals were studied.
